We need to run experimental projects to answer that question properly. The advice we'll provide to our minister is that the science community is going to run a series of experiments on that very issue. We're going to find out what they say. We're going to generate our best scientific advice. In a couple of places, we are going to say we don't know the answer. So we will tell the minister that our advice is based on a certain level of confidence and that there are some unknowns. We will tell the minister what these are and how we propose to tackle them. We don't feel comfortable saying it's all marvellous or all horrible. People who gravitate towards those extremes are welcome to do so, but DFO science will not go there.
